DOCUMENT NUMBER:

TITLE:
Locational Data Policy for Water Allocation Program and the Water Use
Data System
EFFECTIVE DATE:
November 4, 2006
AUTHORITY:
Water Rights Law of 1939;Water Resources Planning Law of 2002;
eFACTS locational data standards
POLICY:
Locational data generated by Water Use Planning Program staff or
locational data submitted for the Water Allocation Program, Act 220
Registration or Water Use Data System (WUDS) must meet the
Department of Environmental Protection’s (DEP) policy goal of a
10-meter/32.8 feet or better level of accuracy.
PURPOSE:
The purpose of this policy is to standardize the minimum acceptable level
of accuracy for locational data for water resources facilities.
APPLICABILITY:
Applies to all locational data entered into eFACTS directly or through the
WUDS interface for primary or subfacility locational data contained on
Water Allocation Permit applications or Act 220 Registrations or other
Division of Water Use Planning forms that collect locational data.
DISCLAIMER:
The policies and procedures outlined in this guidance are intended to
supplement existing requirements. Nothing in the policies or procedures
shall affect regulatory requirements.
The policies and procedures herein are not an adjudication or a regulation.
There is no intent on the part of DEP to give the rules in these policies that
weight or deference. This document establishes the framework within
which DEP will exercise its administrative discretion in the future. DEP
reserves the discretion to deviate from this policy statement if
circumstances warrant.

Introduction
DEP has developed a policy establishing standards and requirements for collecting and documenting
latitude and longitude coordinates and elevation data for facilities, sites, monitoring points, and other
DEP regulated entities or locations (refer to the Locational Data Policy, Document ID: 013-0830-003
available on DEP’s Web site at www.depweb.state.pa.us). Each DEP program is required to establish
program-specific guidance necessary to facilitate the collection and distribution of this information.
While the value of obtaining locational coordinates will vary according to individual program
requirements, the method, accuracy and description of the coordinates is required to be documented.
The Division of Water Use Planning has established the following procedure for obtaining the required
locational information. The general locational procedures have been used by the Division since 1981.
This technical guidance combines the general procedures with the advances in mapping technologies.
Locational Data Collection
Locational data generated by Water Use Planning Program staff or locational data submitted to the
Water Allocation Program or an Act 220 Registration must meet DEP’s policy goal of a
10-meter/32.8 feet or better level of accuracy.
All program forms requiring latitude and longitude data will be modified to include the method used to
identify the location, the location reference point, horizontal reference datum code and description (if
applicable), and the level of accuracy achieved (metadata).
The use of Global Positioning Systems (GPS) is the preferred method to obtain latitude and longitude to
accurately locate the permit areas, facilities, and sub-facilities. Please note that the use of recreational
GPS units do not meet this level of accuracy unless they employ Wide Area Augmentation Systems
(WAAS) technology. However, if GPS technology is not available, the use of manual methods (i.e.
mapping software or measurement of latitude and longitude coordinates on USGS 7.5 topographic
maps) is acceptable. Manual methods should be used only when absolutely necessary and should
ultimately be eliminated as a method for obtaining locational data.
The locational data for a primary or subfacility must be obtained for the locations identified in
Appendix A. Appendix A contains a listing of all reference points collected for either a water allocation
permit application or an Act 220 registration or primary or subfacility information collected for the
Department’s Water Use Data System (WUDS) and eFACTS.
Documentation
To implement this policy, managers must direct staff, to collect and document, at a minimum, the
following required information. The information noted with a circled number corresponds to the input
screen shown below.

1.
Latitude Measure – The measure of the angular distance on a parallel north or south of the
equator.
1
2.
Longitude Measure – The measure of the angular distance on a meridian east or west of the
prime meridian.
3.
Horizontal Accuracy Measure – The measure of the accuracy in feet of the latitude and longitude
coordinates. (Not required at this time)
2
The format for representing this information is:
+ DD MM SS.SSSS (latitude)
- DDD MM SS.SSSS (longitude)
Where:
Latitude is always presented before longitude
DD represents degrees of latitude; a two-digit decimal number ranging from 00 through 90
DDD represents degrees of longitude; a three-digit decimal number ranging from 000
through 180
MM represents minutes of latitude or longitude; a two-digit decimal number ranging from 00
through 60
SS.SSSS represents seconds of latitude or longitude, with a format allowing possible
precision to the ten-thousandths of seconds
+ specifies latitudes north of the equator and longitudes east of the prime meridian
- specifies latitudes south of the equator and longitudes west of the prime meridian
4.
Horizontal Collection Method:
3
Global Positioning System Differential (GPSDF)
Raindrop Tool GIS Application (RNDRP)
EMapPA GIS Application (EMAP)
EFACTS Spatial GIS Application (EFACT) – defunct
Map Interpolation of USGS 7.5 minute Topographic Map (ITPMP)
5.
Horizontal Reference Datum – the name that describes the reference datum used in determining
lat/long coordinates.
WGS84 – World Geodetic System of 1984 (recommended) (formerly GEO84)
4
NAD83 (Conus) – North American Datum of 1983
NAD27 – North American Datum of 1927
6.
Vertical Reference Datum/Altitude Datum Name – The name that describes the reference datum
used in determining elevation. (not required at this time)
NAV88 – North American Vertical Datum of 1988
NGV29 – National Geodetic Vertical Datum of 1929
392-0830-001 / Final November 4, 2006 / Page 2

7.
Reference point – A reference point describes either a primary or sub facility for which the user
is collecting locational data. Appendix A contains a list of primary and subfacilities for which
locational information is collected for WUDS. WUDS captures detailed information about
various facilities. There are fewer eFACTS kind and type records than WUDS. For instance
eFACTS only contains classification of SWW and GWW. In WUDS an eFACTS GWW is
further classified according to its facility designation such as well, spring, quarry etc.
8.
Geometric Type – Point (default) – The point referenced by geographic coordinates
6
5
9.
Date of collection – This represents the date the locational information was recorded or
determined. The date must be recorded for all locational determinations whether GPS or GIS.
7
10.
Primary or Subfacility name
11.
Primary or Subfacility eFACTS ID – if known
12.
Primary or Subfacility WUDS ID – if known.
13.
Source Map Scale Number – The horizontal map scale of the paper if using Horizontal
Collection Method (INTMP)
